Church Team #2
In continuing Team #1's criticism of Copernicanism, show that Galileo does not decisively solve the problems of motion implied by a rotating Earth.
For further depth, discuss:
[in coordination with Team 4] Galileo's desperate efforts to provide physical evidence related to the Earth's motion, exemplified in his unsuccessful effort to enlist Gilbert's arguments (end of Day 3) and/or in his dismissal of Kepler's theory of the tides.
- Discuss the weaknesses in Galileo's concept of falling bodies.
- Discuss how Galileo ultimately fails to solve the problem of motion with his concept of relative motion. Underscore the common sense of direct observations (for example, calculate the proposed velocity of the earth in Rome?).
- Discuss the weaknesses in Galileo's theory of the tides (especially their timing) and Kepler's alternative (1609)
